The Flomatic Glen-Flo® GF3501 GFAVB 1" atmospheric vacuum breaker is designed to protect potable water systems from back-siphonage conditions caused by negative pressure. This device is intended for intermittent potable water service and is not designed for continuous pressure applications.

Specifications:

Max Pressure: 125 psi

Max Temperature: 180°F (80°C)

Standard: ASSE 1001

Connection: 1" Female NPT threaded

Weight: 2 lbs

Operation: Under normal flow conditions, the valve remains open to allow water to pass through the device. If a back-siphonage condition occurs, the atmospheric vent opens to break the vacuum and prevent contaminated water from being drawn back into the potable water supply.

Construction: The GFAVB features a durable body with corrosion-resistant internal components designed to provide reliable performance in irrigation and plumbing applications where atmospheric vacuum breakers are required.

Standards & Compliance: Complies with ASSE 1001 requirements for atmospheric vacuum breakers.

Applications: Irrigation systems, hose connections, and plumbing fixture supplies where protection against back-siphonage is required and continuous pressure is not present.
